Given numbers are 411, 378, 816, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 378) = 51786
GCD(411, 378) = ( 411 x 378 ) / 51786
= 411 / 378
= 411
Step2:
LCM(3, 816) = 816
GCD(3, 816) = ( 3 x 816 ) / 816
= 3 / 816
= 3
Step3:
LCM(3, 217) = 651
GCD(3, 217) = ( 3 x 217 ) / 651
= 3 / 217
= 3
So, Greatest Common Divisor of 411, 378, 816, 217 is 1
